Typically something like this occurs when templates are nested "too deep". Try using the compiler switch to increase template depth to 256 levels. I forget what the template switch name is - you'll have to look it up. You can also look a the bjam files for tests and build. Respond here if the problem can be fixed this way.

Unfortunately there is no such switch in MSVC. As far as I can understand, bjam's "c++-template-depth" argument is not used when building with MSVC.

Anyway, how is it that an object tree just 5 levels deep is deep enough to hit the compiler limit when Boost serialization is used?
